Fixed test failure on innodb_encryption

After MDEV-13583: Improvements for MTR rebootstrap introduced in
MDEV-12042 bootsrap correctly creates mysql/innodb_table_stats
and mysql/innodb_index_stats InnoDB tables before innodb_encryption
test starts. These tables are also encrypted or decrypted, thus
we need to wait also these tables (if not we could randomly
get different results as system tablespace and these tables
are encrypted or decrypted in parallel).
